I don’t have real-time access to TV listings in this moment, but I can point you to the most likely ways to find today’s Manchester United channel quickly:

• Check official broadcast partners for your region. In the UK, Man Utd League matches are typically shown on Sky Sports or TNT Sports (formerly BT Sport/others) depending on the competition and schedule. For women’s or youth fixtures, there can be different channels or streaming options.
• If you’re in the United States, Premier League games are commonly streamed on services like Peacock or USA Network/NBC platforms, depending on the match and window.
• For live updates and exact channel, quickly search “Manchester United today channel” plus your country. Major outlets often list the exact channel and start time for today’s match.

If you’d like, tell me your country and whether you mean a men’s Premier League game or a women's/youth fixture, and I’ll give you the most probable channels and times for today.
